Imagine the world a quieter place...Of the human senses only hearing is hard to control. If you see something ugly you can turn your head or close your eyes. if you smell something bad you can breathe through your mouth... closing your ears is the real problem. On top of this audio from multiple sources create interference. When orchestrated it can be harmonic but in public spaces diferent sources of audio is not coordinated, creates disharmony resulting in noise.
